Pricing & Profit calculator
SEO ROI Calculator
Estimate potential monthly revenue and ROI from SEO spend using expected leads, conversion rate, and average sale value.
Why use it
- Useful for turning SEO spend into a simple lead, sales, and revenue model before committing budget.
- This is only an estimate. Real SEO performance varies with ranking, demand, sales process, and time to result.
- The calculator uses revenue, not profit margin. If your delivery cost is high, the real commercial return may be lower.

Important note
BizTools.au is designed to make business numbers easier to check, but calculator outputs still need judgment and real-world context.

- Examples and summaries are provided for general information, not legal, tax, accounting, payroll, or financial advice.
- Before relying on a result for a real decision, check your assumptions and get qualified advice where needed.
How it works
Understand the formula before you use the result
The calculator uses a simple working formula so you can sense-check the result quickly and explain it clearly inside your business.
SEO ROI formula
Sales = monthly leads × conversion rate
Revenue = sales × average sale value
ROI % = ((revenue - SEO cost) / SEO cost) × 100
Revenue-to-cost ratio = revenue / SEO cost
This keeps the model simple so you can pressure-test SEO assumptions without overstating certainty.
Worked example
See the numbers in a realistic scenario
Use the example below as a sense check when you compare the calculator result to a real quote, sale, or pricing decision.
Worked example
Worked example: testing monthly SEO spend
A business plans to spend $1,500 per month on SEO, expects 30 monthly leads, converts 20% of leads into sales, and averages $1,200 per sale.
- Monthly SEO cost: $1,500
- Estimated monthly leads: 30
- Lead-to-sale conversion rate: 20%
- Average sale value: $1,200
Calculation steps
- Sales = 30 × 20% = 6 sales
- Revenue = 6 × $1,200 = $7,200
- ROI = (($7,200 - $1,500) / $1,500) × 100 = 380%
- Revenue-to-cost ratio = $7,200 / $1,500 = 4.8x
On those assumptions, SEO would generate about $7,200 of monthly revenue, leaving $5,700 above the SEO spend.
FAQ
Common questions about the seo roi calculator
These are the practical questions operators usually run into when they apply the result to a real business decision.
Is this a guarantee of SEO results?
No. It is only a planning estimate. Rankings, demand, enquiry quality, sales follow-up, and timeframes all affect actual performance.
Why does the calculator use revenue instead of profit margin?
It keeps the model simple and transparent. If your delivery costs are meaningful, you should still test margin separately before relying on the result.
What if my conversion rate is uncertain?
Run a few scenarios. A conservative, expected, and optimistic conversion rate will usually give a more useful planning range than one single assumption.
